Effect Of Small Racket Face Exercise On The Effect Of Baseline Forehand Stroke And Executive Function Of College Tennis Students

In tennis,stroke accuracy,stroke stability,and stroke power are the basis of technique,and executive function is crucial in tennis,so how to improve students’ tennis technique and executive function through practice is of great importance in tennis teaching and training.Objective: This study was conducted to investigate the effects of small-sided practice on the baseline forehand stroke and executive function of tennis students by comparing the differences between the experimental and control groups in terms of accuracy and depth of the baseline forehand stroke and behavioral and brain mechanisms during the behavioral inhibition task.Methods: Twenty-four students from two tennis-specific classes were selected and divided into an experimental group(n=12)and a control group(n=12).The experimental group used the small-sided practice intervention for 14 weeks,and the control group was taught normally.(2)A behavioral inhibition task was performed to collect correctness and response while the f NIRS near-infrared brain imaging system was used to capture hemodynamic changes in the subjects’ prefrontal lobesResults:(1)After the experiment,the statistical difference between the experimental and control groups(p>0.05)was not statistically significant,and the small-tap face exercise did not improve physical fitness.(2)After 14 weeks of small-sided tennis racket practice,there was a statistically significant difference between the experimental group and the control group in terms of baseline forehand stroke effect.Compared with the control group,the experimental group scored higher in baseline forehand stroke accuracy(p<0.01)and baseline forehand stroke depth(p<0.05)after small-sided practice,indicating that small-sided practice can improve the accuracy and depth of the subject’s stroke by improving the accuracy and depth of the subject’s stroke.This reflects the important role of small-sided practice in the effectiveness of tennis baseline forehand strokes.(3)After 14 weeks of small-sided practice,in the behavioral index results: the correct rate and reaction time of the behavioral inhibition task were statistically significantly different between the experimental group and the control group,and the reaction time of the behavioral inhibition task(p<0.01)was significantly shorter and the correct rate(p<0.05)was higher in the experimental group compared with the control group,which indicated that the small-sided practice was effective in improving the subjects’ f NIRS results:the level of Oxy-Hb activation in the left dorsolateral prefrontal(p<0.01)and right dorsolateral prefrontal(p<0.01)was significantly higher in the experimental group than in the control group,and this result indicates that the ability to mobilize attentional resources was improved after small-tap face practice,resulting in significant activation of the dorsolateral prefrontal.Conclusions:(1)Small racket face practice had a positive effect on the baseline forehand stroke effect and brain executive function of tennis-specific students,mainly in the form of improved baseline forehand stroke accuracy and depth scores and improved performance on behavioral inhibition tasks.(2)Oxy-Hb levels in the left dorsolateral prefrontal and right dorsolateral prefrontal were significantly activated in the experimental group,indicating that the left dorsolateral prefrontal and right dorsolateral prefrontal brain regions were associated with improved executive function in tennis students with small racket face practice.(3)Small racket surface tennis racket can better promote the development of motor skills,and the use of assistive devices can effectively improve the quality of teaching.
